Sql 如何将行插入到值中

有一个带有值的表

CREATE TABLE #tbl 
    (
       id int  identity(1,1),
       object_type int ,
       object_id nvarchar(50),
       refl nvarchar(4000)
    )

refl值具有如下参数：

<prov><CProv><object_type>1</object_type><object_id>152</object_id></CProv></prov>
<prov><CProv><object_type>0</object_type><object_id>150</object_id></CProv></prov>
<prov><CProv><object_type>0</object_type><object_id>156</object_id></CProv></prov>
<prov><CProv><object_type>1</object_type><object_id>172</object_id></CProv></prov>

使用T-SQL，然后说

WHERE refl in IN yourSplitFunction(@val)

试试这个

DECLARE @val NVARCHAR(4000) 
SELECT @val = COALESCE(@val + '', '') + refl
FROM #tbl

SELECT @val

---

你的意思是说你的tbl表中有4行吗？@hardcore程序员是的，有4行非常感谢你节省了我的时间

DECLARE @val NVARCHAR(4000) 
SELECT @val = COALESCE(@val + '', '') + refl
FROM #tbl

SELECT @val
